It's only an alternative if you have a backing swap device. zram does not have this requirement, so (aside from using no compression) it's basically the only solution for some scenarios (e.g. using entire disk(s) for ZFS).
- kragen 1y agoCan't you use a ramdisk as your backing swap device?
- PhageGenerator 1y agoUsing a ramdisk for zswap is basically just zram with extra steps.
- kragen 1y agoExtra steps are fine if the result works better.
- Ferret7446 1y agoIt is not the same at all. The swapping algorithm can make a big difference in performance, for better or worse depending on workload
- RealStickman_ 1y agoZram is just swap but in RAM. It uses the same algorithms as normal swap
